The advantage of PTFE coatings (for example Teflon) is the non-stick properties of the material, which means applications like commercial bakeware have excellent non-stick / release properties and are super easy to completely clean.

We have created a range of PTFE coating systems with a lot of good things about suit most applications. The function that this coating is usually to be utilized for and also the operating conditions will define the selection of the right coating for the task.

On this blog, we explore some of the benefits in great detail.

NON-STICK AND RELEASE
A PTFE coating used on a component can give excellent non-stick/release properties which is quite simple to clean. This kind of coating is additionally excellent at preventing both hot products from permanently adhering to the substrate and thus is traditionally used from the cookware, confectionery, food processing and bakery industries. PTFE coatings may also be employed for non-stick within the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.

NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, and will not readily wet. This enables the fabric to self-clean. For your semiconductor industry, this property owner vital as it allows all chemical media to run off and stay collected.

TEMPERATURE RESISTANCE
PTFE coatings can service arduous application conditions involving extremes of temperature. They could remain stable at advanced temperatures of +260°C as well as short periods at +290°C. PTFE can be utilized on extrusion dies and sealing of plastic/elastomers where anything else may degrade or cause clogging of molten material. These coatings may also perform at cryogenic temperatures and may remain stable at -270°C.

LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and may achieve very low coefficients of friction, typically from about 0.04 to 0.15. Where oils and grease evaporate at elevated temperatures PTFE remains which is therefore perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. With regard to added abrasion resistance and increased wear life, this kind of coating may be reinforced by building fillers and through combining with a metal sprayed first layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistance against attack from most chemicals so when joined with other fluoropolymers including FEP and PFA greatly enhances the time of the component. PTFE applied being a surface coating will raise the corrosion resistance in the component which enable it to also be enhanced by using primers, other pre-treatments including plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all take advantage of most of these coatings.

ELECTRICAL PROPERTIES
PTFE carries a high dielectric strength, a low dissipation factor, insulating and also surface resistivity, giving protection and uses in numerous electrical applications. Our coatings may also be built to become conductive and utilized as an antistatic coating. Light fittings, connectors, cable guides and portable electrical equipment all take advantage of PTFE.

ANTI-GALLING
PTFE coatings prevent galling and provides excellent bearing properties. Mating surfaces and rotating parts reap the benefits of this coating and help provide minimal maintenance downtime.
